Try looking for the Microsoft TZedit.exe utility. It is not installed with the OS, but is an extended utility you can find on an OS disk (or used to).. There are some exe copies posted around the internet (disclaimers …). It allows view/edit of the time zones.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\E. South America Standard Time

I did a quick search for MS patch, but didn’t see any.
Good luck,

Subject: [firebird-support] Firebird 3 and DST on Windowsw Server 2012

Down here in Brazil DST started that Sunday at 0:00. This year, DST was
due to general elections. To my surprise, today I observed that
is returning a value 1 hour early than local time.

It only affects Firebird 3 running on Windows. For Firebird 2.5 and
Firebird 3 on Linux
everything looks ok.

Has anyone observed such behavior before? Is there a circumvent?
